Modbus Gateway Profile, Overview | Perle Systems STS, SCS specification

Serial Port Profiles

Modbus Gateway Profile

Overview

Each serial port can be configured as either a Modbus Master gateway or a Modbus Slave gateway, depending on your configuration and requirements. If your model supports I/O, see Modbus I/O Access on page 268 for more information on using the Modbus protocol to access I/O data.

Functionality

The Modbus Gateway profile configures a serial port to act as a Modbus Master Gateway or a Modbus Slave Gateway.
